Intermediate levels of Re(ƒ)=constant are shown with thin red lines for negative values and with thin blue lines for positive values. have a peek here

Cody's rational Chebyshev approximation algorithm.[20] Ruby: Provides Math.erf() and Math.erfc() for real arguments.

Esta función, llamada w(x), (también conocida como la función Faddeeva) admite la siguiente expresión: w ( z ) = e − z 2 erfc ( − i z ) {\displaystyle w(z)=e^{-z^{2}}{\textrm This usage is similar to the Q-function, which in fact can be written in terms of the error function.

En forma similar, las En para n pares luego de dividirlas por n! Perl: erf (for real arguments, using Cody's algorithm[20]) is implemented in the Perl module Math::SpecFun Python: Included since version 2.7 as math.erf() and math.erfc() for real arguments. Related functions[edit] The error function is essentially identical to the standard normal cumulative distribution function, denoted Φ, also named norm(x) by software languages, as they differ only by scaling and translation. En menos infinito, tiene el valor de -1. Error Function Matlab

La función error evaluada en más infinito tiene el valor de 1, exactamente (ver Integral de Gauss).
